RAMON CRATER, Israel (Reuters) - A team of six Israeli researchers on Sunday ended a four-day Mars habitat experiment in Israel's Negev desert where they simulated living conditions on the Red Planet, Israel's Science and Technology Ministry said.

The experiment was held near the isolated Israeli township of Mitzpe Ramon, whose surroundings resemble the Martian environment in its geology, aridity, appearance and desolation, the ministry said.

The participants were investigating various fields relevant to a future Mars mission, including satellite communications, the psychological effects of isolation, radiation measurements and searching for life signs in soil.
